This electric guitar was found in sealed locker in an abandoned warehouse. Refuted to once be a storage area for Battelle Memorial Institute, the locker had a Division 961 sticker on it and was accompanied by a Model 503 Fast Rise Generator. Paper work found with the guitar dated it about 1961 and described the oddly levered chamber below the bridge as a Pleiadian Chime. I don't know what it does, why it does it, or if it still functions, but man it's beautiful! It's labeled "Centro-Matic" but I found no other Centro-Matic guitars on record. More reaearch to follow.
